JP 2008-38425 A

However, in the first method disclosed in Patent Document 1, there is a problem that it is difficult to cut, bend, or otherwise perform processing such as fitting the ends of the roof.
Moreover, in the second method, the heat insulating material is not fixed until the roof material is fixed, and there is a risk that the heat insulating material may be displaced or scattered due to strong winds or the like.
Furthermore, in the third method, after fixing the heat insulating material, it is necessary to further fix the roof material with hangers or screws.

Therefore, the present invention provides a horizontal roof structure that can be installed from the water side or from the water side along the slope of the roof foundation, and can be applied to both new construction and renovation. The purpose is to make a proposal.

The present invention has been proposed in view of the above. In the horizontally roofed roof structure in which the roofing material is laid, the holding member also serves as a hanger, and holds the underwater side molding part and the water side molding part of the horizontal roofing exterior material adjacent to each other in the flow direction. A joint holding portion is provided, and the underwater side molding portion of the horizontal roofing exterior material adjacent in the flow direction is provided between the notch surface of the heat insulating material on the water side and the engagement holding portion of the pressing member. The present invention relates to a horizontally-roofed roof structure characterized by having a recessed space that enables pivoting or vertical movement for engagement with a water side forming part.
In addition, the above-mentioned "recessed space that allows rotation or vertical movement" is nothing but a space for installing by rotating or moving vertically.

The present invention also proposes a horizontally-roofed roof structure characterized in that the heat insulating material is laid on the surface of the foundation without gaps in the above-mentioned horizontally-roofed roof structure.

Furthermore, the present invention proposes a horizontally-roofed roof structure (=horizontally-roofed roof repair structure) characterized in that the base surface is an existing roof and the horizontally-roofed exterior material is a roofing material for repair. is.

In the horizontally-roofed roof structure of the present invention, since the surface of the heat insulating material is fixed by the pressing material, there is no fear of displacement or scattering, etc. When constructing the horizontally-roofed exterior material, the notch on the water side of the heat insulating material is eliminated. It is possible to rotate or move up and down to engage the underwater side molding portion and the water side molding portion of the horizontal roofing exterior material adjacent in the flow direction between the surface and the engagement holding portion of the pressing member. Since the recessed space is provided, the horizontal roofing exterior material can be easily constructed from the water side or the water side without limiting the construction direction.
In particular, since the hold-down material also serves as a hanger, it is easy to construct the horizontal roofing exterior material, and a roof surface with high mounting strength can be constructed.
In addition, since the horizontal roof structure of the present invention can be constructed without previously integrating the heat insulating material and the horizontal roof exterior material, there is also the advantage that processing such as cutting and bending of the members is easy.

In addition, when the heat insulating material is laid on the surface of the base without any gaps, a heat insulating layer can be formed without any heat insulating defects.

Furthermore, if the base surface is an existing roof and the horizontal roofing exterior material is a roofing material for renovation, the new roof is constructed without removing the existing roof, so there is no cost for removal etc. can be reroofed at low cost. In addition, since the existing roof is under the new roof, the structure after construction of the new roof will be doubled, and it will be excellent for rain. In addition, it is possible to appropriately select the construction direction by selecting each member having an appropriate shape according to the slope of the existing roof, the state of damage, and the like.

In the horizontal roof structure of the present invention, a heat insulating material is laid on the surface of the foundation, a pressing material that also serves as a hanger is fixed to the surface of the base material by a fixture, and a horizontal roofing exterior material is laid on the outside of the heat insulating material. In the horizontally roofed roof structure, on the surface of the heat insulating material, there is a rotation or vertical movement for engaging the underwater side molding portion and the water side molding portion of the horizontal roofing exterior material adjacent to each other in the flow direction. It is characterized by having a concave space that enables

The heat insulating material, the retainer, and the laterally-roofed exterior material forming the laterally-roofed roof structure of the present invention will be described below.

As described above, the heat insulating material used in the present invention is laid on the outer side of the horizontal roofing exterior material. As such, a recessed space is provided on the surface thereof to enable the horizontal roofing exterior material to rotate or move up and down.
The rotation or vertical movement of the horizontal roofing exterior material refers to the space in which the water side forming part of the horizontal roofing exterior material moves (appropriately rotates or vertically moves) to a predetermined position (arrangement position), and the recessed shape. In the space, the horizontal roofing exterior material is not in contact with the heat insulating material.

It is desirable that this heat insulating material be laid on the base surface without gaps. It is more desirable to be connected to
The surface of the foundation is nothing but the surface of the installation foundation, but refers to the surface of the existing roof in the case of repair.
As such a heat insulating material, a water impermeable material or at least a water impermeable material having a water impermeable treatment on the surface side is preferable. , may be a single layer or a laminate. Moreover, a decorative material such as a glass fiber sheet may be applied to the back surface of the heat insulating material, if necessary.

Further, the pressing material is a member that presses the surface of the heat insulating material and fixes it with a fixture. It also serves as a hanger (holding member) that holds the roofing exterior material.
The holding member is not particularly limited in configuration such as shape as long as it has a holding surface portion along the surface of the heat insulating material. Alternatively, a high-strength aluminum extruded material may be used. Depending on the size and required strength of the horizontal roofing exterior material, a stainless steel plate or plated steel plate, etc., usually having a thickness of about 0.6 to 3.2 mm, may be pressed. It may be formed by molding or the like.
Since such pressing materials are applied at the same time as the laying of the insulating material, there is no fear of displacement or scattering of the insulating material at the time when the pressing materials are attached, and subsequent construction can be performed safely.

Except for the case where the pressing member also serves as a hanger (holding member) for holding the horizontal roofing exterior material as described above, a separate holding member (as a separate member) may be arranged as necessary. However, since the number of members increases, as a matter of course, the holding member is provided with an engagement holding portion for holding the horizontal roofing exterior member as in the illustrated embodiment described later.

Since the engaging and holding portion is formed on the pressing member, the pressing member is provided with a vertical piece having an engaging and holding portion formed on the upper end as in Example 1, which will be described later.
In addition, depending on the material, the heat insulating material often does not have the strength to serve as a hanger (holding member), but there is a concave shape between the notch surface on the water side and the engaging holding portion of the pressing member. Since the space is formed, it is possible to rotate or move up and down for engaging the underwater side molding portion and the water side molding portion of the horizontal roofing exterior material in the recessed space.

Next, the horizontal roofing exterior material used in the present invention is laid on the outside (surface side) of the heat insulating material as described above. It is caused to behave (rotate or move up and down appropriately) in the recessed space and is guided to a predetermined (arranged) position.
As described above, this horizontal roofing exterior material has a water side forming part, and naturally has a water side forming part that engages with the water side forming part on the water side.
The material and shape of such a horizontal roofing exterior material are not particularly limited, and representative examples are surface decorative steel plates, laminated steel plates, plated steel plates, stainless steel plates, aluminum A known metal material such as an alloy plate, a titanium alloy plate, a copper plate, and the like formed into a predetermined shape by roll forming, extrusion forming, or other means can be used as appropriate. Further, the back surface of the newly installed exterior material may be attached with a backing material such as polyethylene foam or glass wool sheet, if necessary, for dew condensation prevention, soundproofing, and fire prevention reasons.

A procedure for constructing a horizontal roof structure using each member of the present invention will be described below.
First, a heat insulating material is laid on the surface of the substrate, and a pressing material is laid along the surface and fixed with a fixture. Subsequently, by repeating this process, a heat insulating layer may be formed. When the holding member also serves as a hanger (holding member) as in the later-described illustrated embodiment, the hanger is placed prior to the laying of the horizontal roofing exterior material.
Next, the horizontal roofing materials are laid. As described above, in the present invention, the holding member also serves as a hanger (holding member). are properly engaged.
At that time, when the horizontal roofing exterior material is constructed from the underwater side toward the water side in the flow direction, the underwater side forming part is engaged so as to engage with the water side molding part of the installed horizontal roofing exterior material. It should be installed together.
When constructing the horizontal roofing exterior material from the water side toward the water side in the flow direction, the water side molding part is engaged with the underwater side molding part of the installed horizontal roofing exterior material. It may be attached, but as described above, the water side forming part is moved (rotated or moved up and down as appropriate) in the recessed space provided in the heat insulating material and attached.

As described above, in the horizontal roof structure of the present invention, since the surface of the heat insulating material is fixed by the holding material that also serves as a hanger, there is no risk of displacement or scattering. Since a recessed space is provided on the surface of the heat insulating material, construction can be easily performed from the water side or the water side without limiting the construction direction. In particular, when construction is carried out from the water side to the water side, the worker does not step on, stain or damage the horizontal roofing exterior material, the cost of scaffolding can be reduced, the construction period can be shortened, and the safety of construction can be improved. In addition, since the heat insulating material and the horizontal roofing exterior material can be constructed without being integrated in advance, there is an advantage that processing such as cutting and bending of members is easy.

In particular, since the hold-down member also serves as a hanger, it is possible to easily install the horizontal roofing exterior member, and the mounting strength is increased.
In addition, when the heat insulating material is laid on the base surface without gaps, it is possible to form a heat insulating layer that does not cause heat insulation loss, and furthermore, it can be easily installed regardless of whether the base is a roof surface or an existing roof. can be constructed.

In the horizontal-roofed roof structure of the reference example shown in FIG. A lateral roofing exterior material 1 is laid on the outer wall, and the surface of the heat insulating material 2 is provided with a recessed space 24 that allows the horizontal roofing exterior material 1 to rotate or move up and down.

As shown in FIG. 1(b), the horizontal roofing exterior material 1 is formed by folding down the edge of the face plate portion 11 on the underwater side (left side in the drawing) to form the underwater side forming portion 12, (right side) is bent up to form a water side molded portion 13, and both molded portions 12 and 13 are molded so as to be engaged with each other.
The face plate portion 11 of this reference example is formed of a horizontal surface, an inclined surface, and a horizontal surface.

As shown in FIG. 1(c), the heat insulating material 2 has a stepped overlapped portion 22 at the lower end (left end in the drawing) of the body portion 21, and the upper end (right end in the drawing) is overlapped with the overlapped portion. It is a backup material having a superimposed portion 23 to be assembled to the water surface, a recessed space 24 recessed downward from the middle on the water side, and a pressing portion 25 along the surface of the pressing material 3 on the water side. be.
The pressed portion 25 of this reference example has a horizontally extending upper surface along the pressing surface portion 31 of the pressing member 3 and the back surface of the engagement holding portion 32, and a water side surface corresponding to the upper half of the overlapped portion 23. On the inner surface connected to the recessed space 24, a hanger-shaped recessed portion 251 is formed along the outside of the water side forming portion 13 of the horizontal roofing exterior material 1. As shown in FIG.

The pressing member 3 has an inverted W-shaped pressing surface portion 31 along the upper half of the pressed portion 25 and the overlapping portion 23 of the heat insulating material 2 in the installed state as shown in FIG. 1(d). It is a through member having an engagement holding portion 32 in which the tip of the pressing surface portion 31 is bent downward. Since the holding surface portion 31 is fixed to the mounting base (existing roof) by driving the fixture 3b, which is a long-leg bolt, the holding surface portion 31 also serves as a fixing portion.

Further, to briefly explain the existing roof, which is the mounting substrate, rafters 5 are arranged continuously on the surface of the flat substrate 4, and a plurality of hangers 7 attached to the rafters 5 are used to construct the existing horizontal roofing roof material. 6 is attached, and a backup material 8 having a rectangular cross section for preventing stepping is arranged on the surface side of each horizontal roofing material 6, forming a substantially flat mounting base surface. .

The procedures for forming the horizontal roof structure (repair structure) of the reference example will be described with reference to FIGS. 2(a) and 2(b). Although the mounting base (6) is shown to be formed in a substantially flat (substantially horizontal) shape, it is assumed to be gently inclined downward from the right side to the left side.
First, after laying the heat insulating material 2 on the existing roof and arranging the above-mentioned backup material 8, the holding material 3 is laid along the surface thereof and fixed by the fixture 3b. Subsequently, by repeating this process as shown in FIG. 2A, a heat insulating layer is formed.
In this reference example, as described above, the right side of the drawing is the upper side of the water and the left side is the lower side of the water. , This heat insulating material 2 is constructed from the underwater side to the underwater side as shown in the figure.

Next, as shown in FIG. 2(b), the horizontal roofing exterior material 1 is laid. The lateral roofing exterior materials 1, 1 adjacent to each other in the direction of flow may be properly engaged so as to be held tightly.
As shown in the figure, in the operation of constructing the horizontal roofing exterior material 1 from the underwater side (left side of the drawing) toward the water side (right side of the drawing) in the flow direction, the horizontal The roofing exterior material 1 is faced with the water side (left side in the drawing) being high and the water side (right side in the drawing) being inclined low, and the water side forming part 13 is appropriately formed in the recessed space 24 formed in the heat insulating material 2. It rotates or moves up and down, and is moved to the arrangement position indicated by the dotted line in the figure (the position where it engages with the hanger-shaped concave portion 251 of the heat insulating material 2).
Although not shown in the area enclosed by the dashed line, the underwater forming part 12 is formed in parallel with the behavior of the above-described water side forming part 13 to form the already installed horizontal roofing exterior material 1 on the water side. After being deformed by abutting against the portion 13 and expanding against elasticity, it is attached by elastic fitting.

On the other hand, when the horizontal roofing exterior material 1 is constructed from the water side to the water bottom side in the flow direction, the horizontal roofing exterior material 1 is faced in an inclined state as described above, and the recessed shape formed in the heat insulating material 2 is applied. It is almost the same in that the water side molding portion 13 is appropriately rotated or moved up and down in the space 24, and instead of being engaged with the hanger-shaped concave portion 251 of the heat insulating material 2, the water side formed on the lower surface side is attached. It is caused to behave so as to engage with the lower molded portion 12 .
In this case, the behavior of the underwater side molded portion 12 is almost the same, and the underwater side molded portion 12 is not engaged with the underwater side molded portion 13 but is attached by being engaged with the hanger-shaped concave portion 251 of the heat insulating material 2 .

Thus, in the horizontal-roofed roof structure (repair structure) of the reference example, since the surface of the heat insulating material 2 is fixed by the holding material 3, there is no fear of displacement or scattering, etc. Since the recessed space 24 is provided on the surface of the material 2, construction can be easily performed from the water side or the water side without limiting the construction direction. In particular, when construction is performed from the water side to the water side, the worker does not step on, soil or damage the horizontal roofing exterior material 1, the scaffolding cost can be reduced, the construction period can be shortened, and the safety of construction can be improved. . In addition, since the heat insulating material 2 and the horizontal roofing exterior material 1 can be constructed without being integrated in advance, there is also an advantage that the members 1 and 2 can be easily processed such as cutting and bending.

In particular, in this reference example, since the pressing member 3 also serves as a hanger (holding member), it is possible to easily construct the horizontal roofing exterior member 1, and the mounting strength is increased. In addition, since the water-side molded portion 13 of the horizontal roofing exterior material 1 is engaged with the hanger-shaped concave portion 251 of the heat insulating material 2 instead of the engagement holding portion 32 of the pressing material 3, the heat insulating material 2 instead of the pressing material 3 is engaged. can also be regarded as serving as a hanger (holding member). That is, the pressed portion 25 provided with the hanger-shaped concave portion 251 is arranged on the back surface side of the pressing surface portion 31 of the pressing member 3, so that the pressed portion 25 (hanger-shaped concave portion 251 ) is borne by the pressing surface portion 31 .
In addition, since the heat insulating material 2 is laid on the base surface (6) without gaps, it is possible to form a heat insulating layer that does not cause heat insulation defects.

Moreover, in this reference example, the mounting base is the existing roof (6), and the new roof (1) is constructed without peeling off the existing roof (6). can be reroofed at low cost. In addition, since the existing roof (6) exists under the new roof (1), the structure after the construction of the new roof (1) becomes double, and is excellent in rain.

In the horizontal roof structure of Embodiment 1 of the present invention shown in FIG. ' and an existing horizontal roofing material 6', and a heat insulating material 2 ' and a pressing material 3 ' are fixed to the surface of the existing roof (6') by a fixture 3b ', and the heat insulating material 2 ' A horizontal roofing exterior material 1' is laid on the outside, and between the heat insulating material 2 ' ( the notch surface 24' on the water side) and the pressing material 3' (the back surface of the engagement holding portion 32') is provided with a recessed space that allows the horizontal roofing exterior material 1' to rotate or move up and down.

As shown in FIG. 3(b), the horizontal roofing exterior material 1' is formed by folding down the edge of the face plate portion 11' on the underwater side (the left side of the drawing) to form the underwater side forming portion 12'. The edge of the side (the right side in the drawing) is folded up to form a water side molded portion 13', and both molded portions 12', 13' are molded so as to engage with each other.
As shown in FIG. 3(d), the heat insulating material 2' is formed by obliquely notching the water side surface of the main body 21' having a substantially rectangular cross section to form a notch surface 24' , and forming a recessed space above the cutout surface 24'. and
The existing roof (6'), which is the mounting base, has rafters 5' continuous to the surface of the flat base (not shown), and a plurality of roofs attached via waterproof sheets 5b laid on the rafters 5'. The existing horizontal roofing material 6' is attached by the hanger 7, and a backing material 6b is attached to the back side of each horizontal roofing material 6' to provide a substantially flat mounting bottom. forms the ground.

As shown in FIG. 3(c), the presser member 3' of Example 1 is a molded body (piece member) having a substantially U-shaped cross section with two vertical surfaces (side pieces) opposed to each other. A pressing surface portion 31' for pressing the heat insulating material 2' extends outward in a flange shape from the upper end of one side piece (left side in the drawing), and extends inward from the upper end of the other side piece (right side in the drawing). An engagement holding portion 32' is formed which is further bent downward in a bent shape. A fixing portion 33 into which the fixture 3b' is driven is provided between the two side pieces. That is, one side piece of the pressing member 3' of the first embodiment functions as the pressing member 3', and the other side piece (engagement holding portion 32') holds the horizontal roofing exterior material 1'. It plays the role of a child (holding member).

The procedure for forming the horizontal roof structure (repair structure) of Example 1 can also be carried out in substantially the same manner as in the reference example. 3(f), which is an enlarged view of the portion surrounded by the dashed line in the drawing, the cutout surface of the heat insulating material 2' provided with the water side molded portion 13' of the horizontal roofing exterior material 1' is shown in FIG. 24' (recessed space) (rotating or moving up and down as appropriate) to engage. Also, although the mounting base (6') is shown to be formed in a substantially flat (substantially horizontal) shape, it is assumed to be gently inclined downward from the right side to the left side.

As described above, in the horizontal-roofed roof structure (repair structure) of Example 1 of the present invention, the surface of the heat insulating material 2' is fixed by the holding material 3' as in the reference example. There is no fear, and since the horizontal roofing exterior material 1' is provided with a recessed space between the notch surface 24 on the water side of the heat insulating material 2' and the engagement holding portion 32' of the pressing material 3' , construction is possible. It can be easily constructed from the water side or the water side without limiting the direction.
In addition, since the heat insulating material 2' and the horizontal roofing exterior material 1' can be constructed without being integrated in advance, the members 1' and 2' can be easily cut and bent.

Furthermore, in this embodiment 1, although the specific configuration is completely different, the holding member 3' also serves as a hanger (holding member) as in the above-described reference example. In addition, the mounting strength is increased.
Moreover, in this embodiment 1, as in the reference example, the base for installation is the existing roof (6'), and the new roof (1') is constructed without removing the existing roof (6'). There is no cost associated with removal, etc., and the entire roof can be reroofed at a low cost.
